Wolfram Language code: Needs["GraphStore`"]

Specify a graph with data about fruits:

Wolfram Language code: ex[s_] := URL["http://example.org/" <> s];
Wolfram Language code: fruitGraph = RDFStore[{ RDFTriple[ex["banana"], ex["color"], "yellow"], RDFTriple[ex["strawberry"], ex["color"], "red"], RDFTriple[ex["cherry"], ex["color"], "red"] }]

Remove all red fruits:

Wolfram Language code: fruitGraph = fruitGraph//SPARQLDelete[RDFTriple[SPARQLVariable["fruit"], ex["color"], "red"]]
